“Those awful things happened to me. I am that girl.”

The woman who was at the centre of the highly-publicised Luke Lazarus case has waived her right to anonymity in an interview with Four Corners, set to air on Monday night.

Saxon Mullins was 18 when, five years ago this week, she met a 21-year-old boy named Luke Lazarus at a Kings Cross nightclub part-owned by his father.

They met on the dance floor and after just four minutes together, Lazarus took her to a lane way behind the club. She told him she wanted to go back almost immediately, the now 23-year-old said in Monday night’s interview.

“And he was like, ‘No, it’s fine’, and I went to move away and he kind of pulled me back and pulled my stockings and my underwear down. So, I pulled them back up and I said, ‘No I really have to go now’.

“He said, ‘Put your fucking hands on the wall’. And… so I did.”

It was the first time she had ever had sex.

“I didn’t know him. And you know, the few things he said to me before we went outside were just nice, calm, normal things and then all of a sudden, after I tried to leave it was, ‘Put your fucking hands on the wall’, it wasn’t, ‘No, please, stay with me’.

“My heart was going at a million miles an hour, I don’t even think I was breathing for a majority of the time. I don’t even know how to describe it,” she said.

There, in that alley way, Luke Lazarus and Saxon Mullins had anal sex; sex she claims, five years on, was not consensual.

At his first trial in 2015, Mr Lazarus was found guilty by a jury of rape and was sentenced to five years in prison. He spent nearly a year behind bars before he was released on bail, when his conviction was quashed on appeal by a judge. In June last year, the Director of Public Prosecutions appealed against the acquittal, only for the bid to fail in November.

In May last year, Ms Mullins, then still unnamed to the public, wrote on social media about the weight of the case and the monumental impact it had on her life.

“I am mad and frustrated and heartbroken. Was it all for nothing? I’ve waited four long years. I’ve stressed and worried and stayed up all night – many many nights – thinking about it,” she said.

Luke Lazarus.

"I lost something that night all those years ago and I've been searching for it ever since," she wrote at the time.

"The reality is this doesn't get to be over for me. I don't get to know who I would be today had this not happened to me, and I mourn for that person. She seemed like she was on her way to being great.

"I don't want anyone to suffer, that would never bring me joy. All I've wanted since that night was to hear the words "I was wrong" and "I'm sorry". An apology for what was done to me is all I was ever after," she said.

Speaking to Four Corners on Monday night, Ms Saxon's best friend Brittany Watts, who was with her on the night she met Mr Lazarus, said her friend hasn't quite been the same since that 2013 night.

"I knew something had happened. I ran towards her and she actually collapsed in my arms,” Ms Watts said.

“It was from that moment that everything in her ... changed. It was almost like she just crumbled. I will never forget that moment.”

Watch I am that girl tonight on Four Corners at 8.30pm on ABC TV or on ABC iView.
